Abstract

Background and Objectives: Field saturated hydraulic conductivity (Kfs) is one of the most important soil properties that considerably contribute to soil quality. However, specifically in the structured soils, the measurement of Kfs is difficult and time-consuming. Therefore, verifying the simple and fast methods for Kfs measurement is needed for effective soil monitoring. This study was conducted to investigate the effect of RING SIZE (rings with diameters of 5.5, 10.88, 16 and 31.8 cm) on the Kfs measured with simplified falling head (SFH) single ring method in a structured clay loam soil. Furthermore, the effect of conventional tillage on Kfs was assessed and the Kfs measured with double ring (DR) method and SFH procedure was compared.Materials and Methods: The simplified falling head (SFH) method of rings with diameters of 5.5, 10.88, 16, 27.83 and 31.8 cm was used. In DR method diameter measuring 83.27 cm and diameter ring buffering 50 cm and infiltration with way costant head was measured. Factor of discrepancy between the values of field saturated hydraulic conductivity (Kfs) was measured with different RING SIZEs with model simplified falling head (SFH) single ring and traditional double ring (DR) methods. Statistical analysis in a completely randomized design between DR method and different sizes were used in SFH. The comparison of the level of five percent by SNK using SAS (9.1.3) was performed.Results: Results showed that while the RING SIZE affected the measured Kfs, the discrepancy between Kfs results of given RING SIZE compared to the smallest RING SIZE (d=5.5 cm) was practically negligible (factor of discrepancy£0.27). The effect of tillage operations on the measured Kfs was substantial (discrepancy between Kfs results of 2.1 to 3.1). The SFH and DR techniques yielded statistically different means of Kfs. However, the discrepancy between the Kfs values obtained with the SFH method using the largest RING SIZE and the Kfs values determined with DR method was practically negligible (factor of discrepancy<0.37). The coefficient of variation of Kfs values obtained with DR was also higher than the SFH measurements.Conclusion: The duration of the infiltration runs with SFH approach was appreciably shorter than the DR method. In conclusion, the mean Kfs values obtained with SFH technique were appropriate to monitor the effect of tillage. Further studies are needed to test the suitability of SFH technique to monitor hydraulic conductivity of various soils for different purposes.
